Quick Summary

Researchers using AI discovered critical vulnerabilities in PHP, a programming language used by about seven in ten websites including Wordpress and Wikipedia. The flaws, dubbed "PHP2shell," have been present for over a decade but are only now being exploited, leading experts to warn of an imminent rise in data breaches. Security fixes have been released, but many website operators are still vulnerable until they update their systems. Users are advised to use unique passwords or passkeys and monitor their financial statements closely due to potential breaches.

Story summary

As of October 21, 2026, critical vulnerabilities were discovered in PHP, a widely used web programming language, prompting European and British authorities to recommend that many websites temporarily go dark. This led to several major sites, including government pages in Europe, the BBC, and other organizations like Wikipedia and Pinboard, being taken offline on Wednesday morning as website operators scrambled to apply security updates or risk potential cyberattacks. The vulnerabilities, rated at a critical severity of 9.2 out of 10, could allow hackers to remotely execute code, potentially compromising sensitive data and networks. Reports suggest that up to 70% of the world's websites may be affected by these issues, as PHP underpins large parts of the internet infrastructure. The discovery underscores concerns about the rapid spread of AI in cybersecurity, with some experts calling it "one of the first areas where we are going to see the harmful impact of AI."

Narrative

There is not much an individual can do about a server they do not control, so the practical advice is the same hygiene that always pays off: - Use unique passwords or even better, use passkeys and a password manager so a breach at one site doesn't unlock your other accounts - Keep an eye on card statements over the coming weeks - Be extra wary of unexpected prompts to log in or download something, even on sites you trust What happened? Yesterday, the organisation behind PHP issued a security alert about the discovery of two "critical" vulnerabilities.
